" acitizen'ofthe Uni-ted States, 'r'e'sidingat' Alhambra, in the countyof LosfAngeles and State ofGalifornia, have invented new and usefulImprovements {in Shade-Adjust- I ers, of which the follo'wingis} a's'pecificahorn type of'shade'rollers'i tion.- e v My inventionrela'tjes to improvements in shade adjusters, more-particularly for window shades which are mounted upon spring rollers and upon which the sameare wound or rolled up by action ofasprin and from which the: same'fareunwound orunrolled against the action of saeh' spring." Tfh'ese rollersare commonly known as the l-li'trts-v My"inv,ention relatesto'improvei'n'ents in the suspension of such ordinary spring roller andits attached shade hereinaftercalled the primary roll'er, from an upperor.

secondary spring" roller of like kind".which is fixed in a certainworking position, as at thetop of a windowf opening, by-nmans offflexible connections, adapted to" be wound upon andunwound from saidupper 01 sec-l ondary roller, and supporting theprimary roller andattached shade'in anew, and suit able hanger for the's'amei' Bythismeans 'it' is possible to shiftlth'e' position of the pa mary roller tostationit'at any part ofthe window opening, whereupon. theatta'chedshade may be unr o'll' ed from the i primary roller to screenor' coverany or all of'the window opening as desired, By this means the upper,lower 'orbeiitei part'ofthe window openlng may be screened, whilellghtmay" pass unobstructedly and ventilation obtain through the lower,upper, or upper and lower parts of the window opening respectively.

The invention has for its objects to provide an improved adjuster of thegeneral character stated, which will be superior in the matter ofsimplicity, inexpensiveness of construction and assembling, durability,facility in adjustment and control, neatness and attractiveness inappearance, and a general superiority in efficiency and serviceability.

I attain these objects by the novel and useful provision, formation,construction, association and combination of parts, members and featuresshown in the accompanying drawings, in which Figure 1 is a frontelevation of the comgametes of midis Patent 1 it P t te fly 29, 1919plete improved shade adjuster constructed and'assembled to embody myinvention, the primaryroller and attached shade within thehanger beingshown in a position relatively near 'the'top of a window opening; F ig;2-isa front elevation ,of 'thelefthand primary roller engaging -memb'erof the hanger, on an enlarged scale,

The secondary roller A is fixed" in bracketsofthe usual type at the topofa window 'iopening, having attached thereto by "their upperextremities flexible connections d and (Z designed to be wound upon andunwound from the secondary roller A in like manner as shades are woundupon and unwound from the Hartshorn type of spring rollers. 03 and dpass through the hanger F at holes 19, and meet at (i The hanger Fpreferably comprises a nonfiexible member 7 and left and right handroller engaging members f and F. f preferably comprises a metal sleeve14 tightly fitting around the left extremity of f and a dependingportion 11 formed at its extremity 16 to aflord a notch adapted toreceive the flattened end or tip of the standard type of shade rollers.f preferably comprises a metal sleeve 15 tightly fitting around theright extremity of f and a depending portion 12 formed at its extremity17 to receive the round end or tip of the standard type Fig." is a'frfonflelevati'on of a hanger er;
